KAK Industry DBC AR-15 5.56/.223/300BLK Bolt Carrier Group – Phosphate/Chrome-Lined
The KAK Industry DBC AR-15 Bolt Carrier Group is designed for shooters running forced reset or active reset-style trigger systems who want improved reliability without requiring heavier buffer setups. Featuring a floating weight inside the carrier tail, the DBC uses a dead blow effect to help eliminate bolt bounce while adding the carrier mass needed for proper function with compatible reset systems.
Successfully tested with systems including the Hoffman Tactical Super Safety, AS Designs ARC-Fire FRS, and Atrius Development FRS, the DBC provides a reliable solution for builders looking to maintain a standard 3 oz carbine buffer setup while improving cycling performance. The M16-profile carrier features an aircraft-grade 8620 steel construction, chrome-lined phosphate finish, and properly heat-treated components for long-term durability.
